Gamma ray-induced decomposition of the binary mixtures of zirconium and thorium nitrates with 2.5, 5 and 10 mol% of V2O5, PbO, ThO2, ZrO2, and MnO2 has been studied at different doses up to 260 kGy. Radiation chemical yield G(NO2−)-values are enhanced by V2O5, PbO, and ThO2 but are decreased... (Read more)
